This invention relates to improvements in lamps and is directed more particularly to a lamp and a support therefor.

The principal object of the invention is the provision of a cooperating lamp and wall bracket whereby the lamp may be supported by the bracket and is characterized by novel means for releasably locking the lamp to said bracket. This is desirable to prevent the accidental or intentional removal of the lamp from the bracket,

With the foregoing and various other novel features and advantages and other objects of my invention as will become more apparent as the description proceeds, the invention consists in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more particularly pointed out in the claims hereunto annexed and more fully described and referred to in connection with the accompa ving drawings wherein:

Fig.1 is a side elevational view of a lamp and wall bracket associated accordin to the invention;

Fig. 2 is a sectional plan view on the line 2-2 of Fig. 1; and

Fig. 3 is a side elevational view of. the stem of the wall bracket.

Referring now to the drawin s more in detail, the invention will be fully described.

A lamp as shown has a base 2, an upright 4 extending upwardly therefrom and a shade 6. The lamp may be of such form as may be desired.

A Wall bracket I has a plate l2 which is ada ted to be secured to a wall or the like in any desired manner.

A stem It extends forwardly from the plate l2 and is secured thereto by means of a screwl5 which extends through the plate l2 and is in threaded engagement with a bore [6 of the said stem.

The outer end of the stem [4 is forked to provide horizontally disposed spaced arms H3. The lamp upright 4 is provided with an annular groove 20 therearound. so as to provide a portion 22 of reduced diameter. Opposite sides of the reduced portion 22 are flattened at 24, as shown in Fig. 2.

The dimension a across the flats 24 is sl ghtly less than the dimension 1) between the ends of the fork members Hi, This is so the lamp may be secured to the support by passing the flats laterally 24 between the ends of the forks l8.

When so disposed, the lamp support maybe turned ninety degrees to the position shown in Fig. 2. The diameter of the reduced portion 22 of the upright 4 is greater than the dimension 1) 2 Claims. (01. zap-52) so that the support may not be moved laterally out of the fork.

To releasably lock the upright in thefork the following is provided: a detent 30 isslidable in the bore it of the stem M and it is pressed forwardly by a spring 32 disposed in saidbore. The forward end of the detent engages in a recess of the upright. as shown in Fig. 2, and releasably holds the upright against turning in the fork.

A manually engageable member 34 on the detent extends downwardly through a slot 36 in the stem 14 and may be engaged to move the detent rearwardly and thereby unlock the upright so that it may be rotated in the fork to facilitate its removal therefrom.

The invention may be embodied in other specific forms without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being ind cated by the appended cla ms rather than by the foregoing description. and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claims are therefore intended to be embraced therein.

What it is desired to claim and secure by Letters Patent of the United States is:

1. The combination of a lamp and support therefor comprising. a lamp having a vertical upright of a certain diameter provided intermediate its upper and lower ends with an annular groove therearound forming a reduced neck and upper and lower shoulders at opposite ends thereof, said neck having opposite fiat parallel sides and circular portions therebetween having a certain radius, a support having a vertical plate and a stem extending horizontally forwardly therefrom provided with spaced arms forming a fork having a circular inner surface with a radius slightly greater than that of said neck, the distance between outer. inner and adjacent ends of said arms being slightly greater than the dimension across the fiat sides of said neck but less than the dimensions across the circular portions thereof and the vertical dimensions of said arms being slightly less than the distance between said shoulders whereby the flat sides of said neck may be passed through outer ends of said arms and the upright then rotated so that the inner surface of the fork substantially surrounds the circular portions of said neck, and locking means to releasably lock said upright against rotation in said fork.

2. The combination of a lamp and support greater than that of said neck, the distance bettween outer, inner and adjacent. ends of said arms being slightly greater than the" dimension the dimensions across the circular portions thereof and the vertical dimensions of'sai'd arms being slightly less than the distance between said shoulders whereby the fiat sides of said neck may be passed through outer. ends, of said armsand. the 20 upright then rotated so that the inner surface. of the fork substantially. surrounds the circular poriiions'of-Qsaid neck; said ste'mand' fork provided with a horizontally disposedi'bore andsai'd' neck in a Hat; side thereof provided with a socket in alignment therewith, a detent slidable in said bore having a forward end receivable in said socket to hold said upright against rotation, a spring in said bore urging said detent outwardly, said stem provided with a longitudinal slot leading into said bore and said detent provided with a manually engageable part extending through said slot by the means of which said detent may be moved inwardiyrawan from said'f sflllket REFERENCES CITED Theefollawing-rreferences are of record in the file of'this' patent: across the flat sides of said neck. butlessr-than STATES PATENTS Number Name Date 1:,629i089 Beckmann May 17, 1927 1,933,965 Carlson Nov. 7, 1933 EQREIGN' 'FATENTS Number Country Date 3 39;}; Great Britain 1895 $2641 GreatrBritainwuwuun 1885.
